The wavelength of the h-alpha absorption line that you would detect in the star's spectrum will be 54.67 *
nm
If the object is moving towards or away from us with some radial velocity, shifts can be observed in the location of the absorption
since, material is moving towards us a shift to shorter wavelength will be observed
shift = rest wavelength * ( radial velocity / speed of light )
= 656 *
* (250 *
/ 3 *
)
= 54.67 *

Answer:
The sum of PE and KE remains constant
Explanation:
The frictional force is oposing the force that we apply to this mass. Therefore the overall force is

The second principle of physics tells us that the acceleration of a mass is direct proportional to the applied force, the mass of that object being the proportionality constant.

Hence
This isn’t physics assnugget
